String(i,"%08d")

[rgr]

Edit: OK, it should be:
String(i,"%8.0f")


Am I misunderstanding something or is this a bug?

for(i=0, 20) {
LogMsg(String(i)+"="+String(i,"%08d"), LOG_INFO)
}


Manual:
String(123, "%07d") → "0000123"

A bug I think. String(...) reads integers as floats, then passes them ultimately to _vsnprintf_l to create the string (I think). I'm guessing something there rejects the float because of the mis-matching format specifier.

String(i, "%08.0f") will do what you want, at least.

Nowhere there does it say it accepts '%08d' as a valid format string. In fact it states 'the leading '%' and trailing 'f' are required!' (bolded for emphasis).
